Description
本新型係有關於一種液冷頭。特別是有關於一種具有倒置泵的液冷頭。
隨著科技的進步,電子產品日漸普及,並逐漸地改變了許多人的生活或是工作的模式。當電腦運算能力的日益增強,處理器等電子元件工作時的溫度控制越來越重要。
處理器等電子元件在運行時會產生熱量,需要適當冷卻才能達到最佳性能。為了讓處理器等電子元件能保持在理想溫度下運行,目前通常採用液體冷卻或空氣冷卻的方式進行。
以現行液冷散熱方式,工作流體經由管路流入液冷頭,而液冷頭接觸處理器等電子元件的發熱表面,以將處理器等電子元件工作所產生的熱量帶走,進而降低處理器等電子元件的工作溫度,進而提升工作效率。
然而,隨著散熱需求的日益提升,如何能進一步降低液冷頭中的馬達工作溫度,將有助於提升液冷頭的性能與效率,進而提升電子產品的性能與效率。
新型內容旨在提供本揭示內容的簡化摘要,以使閱讀者對本揭示內容具備基本的理解。此新型內容並非本揭示內容的完整概述,且其用意並非在指出本新型實施例的重要/關鍵元件或界定本新型的範圍。
本新型內容之一目的是在提供一種液冷頭,以有效地提升液冷頭的散熱效率,進一步提升電子產品的工作效率。
為達上述目的,本新型內容之一技術態樣係關於一種液冷頭包含有一上殼體、一葉輪、一下殼體以及一鏟齒散熱片。上殼體具有一入水口以及一出水口,而上殼體固定於下殼體之上,且葉輪設置於上殼體與鏟齒散熱片之間。此外,鏟齒散熱片固定於下殼體,且葉輪吸取由入水口進入的散熱液體,使散熱液體經過鏟齒散熱片,再經由葉輪向上,以從出水口排出。
在一些實施例中,葉輪包含有至少一軸流葉片以及至少一離心葉片。離心葉片安裝於軸流葉片的上方,其中軸流葉片將散熱液體由下方向上抽取至離心葉片。
在一些實施例中,葉輪更包含有一輪轂以及一轉動環。軸流葉片安裝於輪轂的周圍,而轉動環則安裝於軸流葉片的周圍。
在一些實施例中,葉輪更包含有複數個永久磁鐵,固定於轉動環的外圍。
在一些實施例中,液冷頭更包含有一中間殼體,且中間殼體包含有一開口,而葉輪穿設於中間殼體的開口。
在一些實施例中,葉輪的至少一離心葉片設置於中間殼體的上方,而葉輪的轉動環穿設於中間殼體的開口。
在一些實施例中,上殼體更包含有一凸緣以及一轉軸,轉軸固定於凸緣之中,凸緣穿過葉輪的一凸緣孔,且轉軸穿過輪轂的一軸孔,以使葉輪繞著轉軸轉動。
在一些實施例中,液冷頭更包含有一定子固定於中間殼體,且定子浸泡於散熱液體之中。
在一些實施例中,定子包含有一上方線架、一下方線架、複數個矽鋼片以及一線圈。矽鋼片固定於上方線架以及下方線架之間,而線圈繞設於矽鋼片,且上方線架、下方線架、矽鋼片以及線圈均浸泡於散熱液體之中。
在一些實施例中,矽鋼片更包含有一防水保護層,塗佈於矽鋼片的外側。在一些實施例中,防水保護層包含有環氧樹脂(Epoxy)、化學鍍鎳或紫外線膠(Ultraviolet curable adhesive)。
在一些實施例中,上殼體更包含有一入水流道凸緣,以形成一弧形入水流道,連通於入水口,以導引散熱液體經由上殼體以及中間殼體流向下方之鏟齒散熱片。
在一些實施例中,入水流道凸緣與上殼體的凸緣之間,形成一排水空間,以容納離心葉片,且排水空間連通出水口,而弧形入水流道位在入水流道凸緣相對排水空間的一側。
在一些實施例中,下殼體包含有一下蓋凸緣、二下蓋入水口以及一下蓋出水口,而下蓋出水口形成在下蓋凸緣的中間,而二下蓋入水口分別位於下蓋凸緣的兩側,且下蓋凸緣套接於葉輪的轉動環。
因此,前述之液冷頭可以利用倒置的抽水泵,將散熱液體由上方入水口,抽向下方的散熱片,且流經定子與轉子,有效地降低水冷頭中散熱片、定子與轉子的溫度,提升液冷頭的散熱效率,且利用葉輪轉動時,散熱液體的壓力,將葉輪向上托起,更能減少葉輪轉動時的磨擦力,進一步地提升液冷頭的工作效率。

第1圖為依照本新型一實施例所繪示的一種液冷頭的***示意圖,第2圖為其側視剖面示意圖,第3圖為俯視剖面示意圖。此外,第4圖為液冷頭的葉輪的剖面示意圖,而第5圖為液冷頭的上殼體的仰視示意圖。
首先參閱第1圖至第3圖,液冷頭100包含有一上殼體110、一葉輪120、一中間殼體130、一定子140、一下殼體150以及一鏟齒散熱片160。上殼體110具有一入水口112以及一出水口114,而上殼體110固定於下殼體150之上,中間殼體130固定於上殼體110與下殼體150之間。而葉輪120亦設置於上殼體110與鏟齒散熱片160之間,且中間殼體130包含有一開口132,葉輪120穿設於中間殼體130的開口132之中。
此外,鏟齒散熱片160則固定於下殼體150,當葉輪120吸取由入水口112進入的散熱液體後,散熱液體首先沿著箭頭方向201進入弧形入水流道290,然後,沿著箭頭方向202向下,經過中間殼體130與上殼體110之間的流道,接著沿著箭頭方向203,流至中間殼體130的下方,並將定子140浸泡於散熱液體,以提升定子140的散熱效果。此外,散熱液體更沿著箭頭方向204進入鏟齒散熱片160的散熱鰭片之間的流道,並沿著箭頭方向205向中間流動,以將鏟齒散熱片160上的熱量帶離。接著,散熱液體被轉動的葉輪120抽取向上,沿著箭頭方向206軸向向上,然後經由離心方向,亦即箭頭方向207,甩出葉輪120,最後再經由箭頭方向208,由出水口114被排出。
在一些實施例中,定子140固定於中間殼體130,且值得注意的是定子140浸泡於散熱液體之中,故可以有效地利用液冷頭100中的散熱液體,進行定子140、葉輪120以及鏟齒散熱片160的散熱,有效地提升了液冷頭100的散熱效率,更能降低定子140、葉輪120以及鏟齒散熱片160的溫度。
在一些實施例中,中間殼體130包含一容置槽250,定子140設置在容置槽250中,且容置槽250之槽口252位在中間殼體130面向下殼體150的一側。

在一些實施例中,葉輪120更包含有複數個永久磁鐵270,固定於轉動環260的外圍,以形成轉子。
在一些實施例中,葉輪120的離心葉片124設置於中間殼體130的上方,而葉輪120的轉動環260穿設於中間殼體130的開口132,且離心葉片124的直徑大於中間殼體130的開口132的直徑,而葉輪120的轉動環260包含永久磁鐵270的直徑則小於中間殼體130的開口132的直徑。
在一些實施例中,上殼體110更包含有一凸緣210以及一轉軸220,凸緣210穿過葉輪120上表面的凸緣孔125,且轉軸220固定於凸緣210之中,並穿過輪轂230的軸孔240,以使葉輪120穩定地繞著轉軸220轉動。於一實施例中,軸孔240為貫穿輪轂230中心的穿孔,但不以此為限。
在一些實施例中,定子140包含有一上方線架144、一下方線架146、複數個矽鋼片142以及一線圈148。複數個矽鋼片142相互堆疊,且固定於上方線架144以及下方線架146之間,而線圈148則繞設於矽鋼片142之上,且值得注意的是,上方線架144、下方線架146、矽鋼片142以及線圈148均浸泡於散熱液體之中,以有效地降低工作溫度。
在一些實施例中,矽鋼片142更包含有一防水保護層,塗佈於矽鋼片142的外側,例如是,環氧樹脂(Epoxy)、化學鍍鎳或紫外線膠(Ultraviolet curable adhesive)等。
在一些實施例中,同時參閱第2圖與第5圖,上殼體110更包含有一入水流道凸緣280向下凸出,以密合於中間殼體130的上表面134,使得入水流道凸緣280與凸緣210之間形成容納離心葉片124的排水空間295,且排水空間295連通出水口114,而入水流道凸緣280相對排水空間295的一側形成一弧形入水流道290,連通入水口112,以有效地導引散熱液體經由上殼體110以及中間殼體130,流向下方之鏟齒散熱片160。
在一些實施例中,輪轂230的軸孔240的直徑大於轉軸220的直徑,以使葉輪120可繞著轉軸220轉動。
在一些實施例中,參閱第1圖與第2圖,下殼體150包含有一下蓋凸緣152、二下蓋入水口154以及一下蓋出水口156。下蓋出水口156形成在下蓋凸緣152的中間,而二下蓋入水口154則分別位於下蓋凸緣152的兩側,換言之,二下蓋入水口154分別位於下蓋出水口156的兩側,而下蓋出水口156則位於二下蓋入水口154之間,以使散熱液體可沿著箭頭方向204,由鏟齒散熱片160的兩端,進入散熱鰭片之間的流道,並沿著箭頭方向205向中間流動,由下蓋出水口156向上流入葉輪120。此外,下蓋凸緣152套接於葉輪120的轉動環260的外側,因此,葉輪120的轉動環260直接連通於下蓋出水口156,以更有效率與穩定地將散熱流體吸入葉輪120。
有鑑於此,所述之液冷頭可以利用倒置的抽水泵,將散熱液體由上方入水口,抽向下方的散熱片,且流經定子與轉子,有效地降低水冷頭中散熱片、定子與轉子的溫度,提升液冷頭的散熱效率,且利用葉輪轉動時,散熱液體的壓力,將葉輪向上托起,更能減少葉輪轉動時的磨擦力,進一步地提升液冷頭的工作效率。
惟以上所述者,僅為本新型之較佳實施例而已,當不能以此限定本新型實施之範圍,即大凡依本新型申請專利範圍及新型說明內容所作之簡單的等效變化與修飾,皆仍屬本新型專利涵蓋之範圍內。另外,本新型的任一實施例或申請專利範圍不須達成本新型所揭露之全部目的或優點或特點。此外,摘要部分和標題僅是用來輔助專利文件搜尋之用,並非用來限制本新型之權利範圍。此外,本說明書或申請專利範圍中提及的”第一”、”第二”等用語僅用以命名元件(element)的名稱或區別不同實施例或範圍,而並非用來限制元件數量上的上限或下限。
雖然本揭露已以實施方式揭露如上,然其並非用以限定本揭露,任何本領域具通常知識者,在不脫離本揭露之精神和範圍內,當可作各種之更動與潤飾,因此本揭露之保護範圍當視後附之申請專利範圍所界定者為準。
